Waiter! Waiter! More engines please!

The Libromancers help set up the main combo lines, gives you a link 2, and sets up 1 negate without using your normal summon: Use the libromancers to search each other + Doombroker, then link off the libromancers on board to special summon ASHLAUN U1000, use ASHLAUN's effect to reveal Doombroker and search Cyber Angel Benten.  Activate Libromancer First Appearance to ritual summon Doombroker using Benten, then use Benten's effect to search Diviner of the Herald.  Now use Doombrokers effect to set Libromancer Intervention from your deck to one of your center 3 spell & trap zones.  

Now heres the main line:

1. Normal Summon Diviner sending Herald of the Arc Light, then use Arc Light to search Ame no Habakiri no Mitsurugi.  
2. Use Habakiri's effect to special Mitsurugi no Mikoto, Saji from your deck and tribute your Diviner.  Use Diviner's effect to special summon Poissonniere de Nouvelles from deck, then chain Saji's effect to search Mitsurugi Ritual from deck.  Use Poissonniere's effect to search Nouvelles Recipe Book from your deck.  
3. Activate Mitsurugi Ritual's 2nd effect to special summon Habakiri sending Mitsurugi no Mikoto, Kusanagi and Night Sword Serpant from your deck to the GY.  Activate Kusanagi targetting Mitsurugi Ritual, then activate Night Sword Serpant's effect to special itself.  
4. Activate Recipe Book.  Then, activate Mitsurugi Ritual's 1st effect to special summon Ame no Murakumo no Mitsurugi from deck by tributing Habakiri on field.  Activate Recipe Book targetting Murakumo to search Chef de Nouvelles, then activate Habakiri's effect in grave to search Mitsurugi Great Purification from deck and to special summon itself.  Set Purification in one of the center 3 spell & trap zones.  
5. (NOTE: you can do this before step 4 if you did the Libromancer combo to insulate against Nibiru, the Primal Being) XYZ summon Evilswarm Exciton Knight using Saji and Night Sword.  Link off Exciton to make Fiendsmith's Requiem,  then use Requiem's effect to special Lacrima the Crimson Tear's effect to send Fiendsmith Engraver from deck to GY. Use Lacrima + Habakiri to link summon Fiendsmith's Sequence.  Use Sequence's effect to fusion summon Aerial Eater using Exciton and Engraver as material.  Activate Aerial Eater's effect to send Engraver back to GY.  If you did the Libromancer line you can link off Sequence + ASHLAUN to make A Bao A Qu, the Lightless Shadow, otherwise make S:P Little Knight using Poissonniere + Sequence.  Use Engraver's effect returning Sequence to special summon himself.  Then, XYZ summon D/D/D Wave High King Caeser using Aerial Eater + Engraver.  (NOTE: you now have Lacrima in grave to special Requiem on your opponents turn, then use Requiem to summon Lacrima to send Fiendsmith in Paradise.  You can use Paradise to send Fiendsmith's Desirae for removal if needed).
6. Now you can scale Chef and activate his effect to search whatever you need for beginning Nouvelles combo.
